UNITED STATES PATENT OFFICE;

THOMAS remit nus'rnen, or wnmme'roiv, NEW ZEALA FASTENER AND RETAINERFOR CASEMEN'I S, DOOBS, THE LIKE.

dows, Doors, andthe likeg'and I do hereby I declare the following to bea full, clear, and exact description of the same.

The object of this invention is to provide improved means for retainingwindows and doors at any desired position, and also to provide a cheaperand more compact device which willat the same time be readilyextensible, andtheretore, form a better stay when the door or window isonly slightly open, and which will, when. desired, be detachable.

According hereto on the window or door post isinounted a slottedrockingshaft or the likein. which one-end of the stay is suitably mounted, theother end being pivoted to a rocking shaft orthe like on" the windowsash or door. The stay may be in single part. or in two or moreextensible A locking latch maybe mounted upon the pin by which the stayis attached-to the rockingshaft upon the sash. Convenient means areprovidedby which the stay can be maintained at any desired position onthe slotted rocking shaft thereby enabling the windows to be retained atany desired position. A countersunk holeis provided on the slottedrocking shaft by which the stay maybe inade detachable and othercountersunk holes may be provided at certainset positions to be anadditional security agalnst slipping.

Figure 9, is an elevation of a modified form of fastener.

Figure 10, is a side-view of Figure 9.

Figure 11 is a sectional view-showing the manner in which the shoe can.be clasped over the rocking shaft.

In the drawings, the rockingshaft 1 is slotted at 2 and'is looselymounted on brackets 3 and 41 attached to the frame 5 of the window. Thestay 6 is provided at one end with a hook 7 (see Figures 1 and P) bywhich it maybe hooked upon a screw-pin 8 passing through the saidrockingshaft and provided with ahead 9 adapted to be fastenedby the screw-pinSinto a countersunk hole 10 in the stay 61sec particularly Figures '2 and3). A knurled or milled nut 11 is threaded upon the screw-pin 8-tocontrol the head in the countersunkhole 10 and V to enable the staytogbe retained at any desired position with regard to the slot 2 uponwhich the stay slides. The object of the said countersunk hole 10 (seeFigures 1 2 and 3) is to retain the stay securely when the milled nut 11is but slightly, unscrewed.

By unscrewing the milled nut 11 the head 9 can bev pushed out of thecountersunk hole 10 and the stay hook may belifted oil" the screwpin 8and gthe window may thus be opened to the full extent independently or"the stay. p i

Another rocking shaft is mounted in brackets 13and Men the window 15,and in such rocking'shaft is pivoted at 16 one end i of the extension 17of the stay 6. A locking latch '18 is also mounted on the pivot 16 andprovided with a lifting knob or handle 19 for operating the latch thehooked portion 20 of which looks over the bracket In Figure 3 is shown asectional view of the milled nut 11 which ismounted upon the screw-pin 8of which the portion 21passing through the outer shoe 22 andtheinnershoe 23 is. squaredylhe outer shoe 22 provides a suitablebearing surface for the end of the stay 6, while the inner shoe 23actsasa steadyingdevicefor thesscrewpin 8,. and thereby presents alarger braking surface when the milled. nut 11 is tightenedr The stay 6being provided with an extension 17 enables the said stay to be shorterand more compact and when set at the shorter length affords a betterstay when the window 15 opened a slight distance onl The exten sion17may be dovetailed in t e stay 6; The extension 17 is controlled by themilled nut 24 upon a screw-pin 25 which is referably squared when itpasses through t e slot 26 in the extension 17 (see Fimires 1 and 2).The said pin may be provided with a head 27 and may be fitted in acountersunk hole in the back of the stay 6. The milled nut 24 whentightly screwed will, at the end of its extension 28, bear against theextension 17 of the stay 6. y

The body of the rocking shaft 1 ma be made U shaped in section asindicate in Figure 3, in which case it may be readily stamped out ofsheet-metal, the end of course being rounded to fit in the brackets 3and 4. The rocking shaft 12 may be similarly constructed and, ifdesired, the other parts may also be made of sheet-metal. The end of thebracket 3 at 29 is rounded or bevelled to enable the hook 20 of thelatch 18 to trip over it readily when the window is being closed.

i It will be noticed on referring to Figure 1 that the pivoted end ofthe latch is partially rounded, the square portion 30 being left inorder to prevent the latch from fallin below the osition indicated inthe drawings.

' The roc ing shaft 12 together with the lows brackets 13 and 14 may beencased in a sheetmetal tray 31- if desiredfto enable it to be readilyfitted in position.

-: The operation of the device is as fol- Referring to Figures 1 and 2,in which the window is shown closed, the latch 18 is lifted from thebracket 3 and the milled nut 11 being loosened the end of the stay 6,together with the shoes 22 and 23, and screw-pin 8 and the milled nut 11will slide along the slot 2 by means of the in 8 in the rocking shaft 1when 'the'win ow ispressed outwards, as indicated more particularly inFigure 5. When the window is thus opened it may be retained atanydesired position by securing the milled nut 11 against the outer face ofthe rocking shaft 1( When the pin 8 reaches the opposite end of the slot2 if it is desired to open the window further, the extensible slidingportion 49 of the stay 6 is brought into use by releasing the milled nut24 until the extension 17 is brought to its maximum, when the milled nutis tightened (see Figure 4), and the window is thereby locked.

y A modified form of the invention isfiillusftrated in Figures 6, 7 and8,"-in which the i i i fstaymay be retained at a horizontal orapproximately horizontal position when the window is but slightlyopened, thereby affording a'better stay. In this form of the inventionthe slot 26 of the extensible portion 17 of the stay 6 is made open atthe end 32 that projects into the room and another nut '11 is partiallyunscrewed and the head 9 released from the countersunk hole 10, the

stay 6 may be slided into the position shown in Figure 6 and may be heldin position by the milled nut 11, as before. In this case 1t may bedesirableto provide means whereby themere lifting of the head 9 out ofthe countersunk hole 10 will not entirely un fasten the stay 6 from therocking shaft 1, and with this object feet or projections 34 areprovided which project from the end of the stay 6. By further unscrewinthe milled nut 11, soas to enable the head 9 to clear the feet 34, thestay may be detached and the window opened to its maximum distance,independently of the stay.

If desired, the fastener may be constructed in the form shown in Figures9 and 10 which case both the stay and the fastener may be made straight.In this case the rocking shaft 35 is located underneath the stay 36which is provided with an extension 37 as indicated in Figure 10. Theend of the stay 6 or of the extension 37 is pivoted at 38 to a hingedpiece 39 which takes the place of the similar rocking shaft 12 shown insion 37in the same manner as previously,

and the latch 40 is also provided with a stop to prevent it fromfalling'below the position shown in'Fig'ure 9. The shoe 43 is placedover the rocking shaft 45 and the rocking shaft maybe provided with aflange 44' upon which the shoe is turned over at 45 indicated in Figures9 to 11.

As shown in Figures 9 and 10 the nut 46 threaded upon the pin 47controls the movement'of the stay 37 in a similar manner to the nut 11shown in Figures 1 to 6, the pin 47 being squared at the portion 48shown by crossed lines in order to prevent the pin from turning.
